REVERSIBLE CASEMENT -WINDOW.

Application 'led April 7, '1927. SerialtNo. 181,784.

, The invention relates to easement windows -ot the type in which 4the sash is reversible, .permitting easy cleaning 'of yits y-outer side withoutdanger orfeiiposure. n

`Speciiically, the invention relates to reversible easement windows in whichlthe sash is provided with bearings rotatably receiv- Aing a shaft whose ends vare provided with Vpi-nionsengaging ranie-carried racl; bars, j said `pin'ions traveling :along said(V rack bars *as the sash is moved to `either of its lrela- =tivelyreversed positions; and one aim ot. the

invention isrto .provide means for locking the shaft against turning with respect to the sash when desired, thereby holdingthe'pin- Vions Vagainst traveling along the rack bars. Thus, when the sash is in a desired open position, it cannot shift toward either side 'of the trame and it may be held against swinging by conventional means.

A lfurther-object of the invention is to provide. `novel means for mounting a bolt which is used to lock the shaft in the manner above referredV to.

`Still another aim is the provision of unique andadvantageous means for Ymounting thesash 'and'holding the pinions in mesh with the rack bars.

With the foregoing in view,"the invention 3" resides Vin the novelA subject matter hereinafter described'and claimed, the 'description -being supplemented byy the accompanying 'drawings -Figpl is a side elevation'ot a window constructed in accordance withour invention.

In the draw-ings above brieilypdescribed,

a trainejF is shown, whose upper portion EJ is vprovided with twoparallel, lhorisontally spaced rails 14C, preferably `tormedof T-iron, the ends of these railsbeing spaced apartby sleevessuch Ias 15,'o`t Figs.

This means 18 may either consist of single angu- Vlarplate or of apluralityoi angular straps,

AA tubular shaft 27 'rotatably surrondsfthe shatt'QS and'isprovidedat its 'upper 'and lower ends fwith pinionsfQS-QSQ, meshing with therack bars 17-20, an'antiifriction bearing 29 'beingjpreferably interposed bev30 denotes Ythe sash, said 'sash being ings and th-e pinions 28-284, anti-friction bearings 32-32a are preferably employed. In the present showing, the sash is of hollow, metal construction and the bearings 3l-31a are provided with anchoring portions Sii-33a which are snugly secured in end portions of the upper and lower rails Sb-343, of said sash. The shafts 23-27 are received in one of the hollow vertical rails 35 of the sash 30, and this rail is provided with a detachable section 36 opposed to the adjacent ends of the rails 34E-34a. This section 36 is detachably secured to the body portion of the rail 35, by screws 37, and other screws 38 may be employed to secure the anchoring portions 33--33a of the bearings S31-'31a rigidly within the rails 34-341.

The detachable rail section 36, the location of the shafts 23-27 in the vertical rail 35, and the detachable anchoring of the portions i3- 33a of the bearings, inthe rails E34-34a, is of great advantage in assembling or disassembling for repairs, as well as producing a compact, protected, durable and efficient construction. Y

The bearings 31-3123 possess a number of features in common and hence the same description, with somevariations, will suffice for both of them. In connection with Ythis description, sce more particularly Figs. 5 to 11 inclusive. Y

39 denotes an outer substantially U-shaped plate Whose bight portion engages the shaft 27, while its arms project yin the same direction from said shaft in spaced parallel relation with each other. The inner end portionof this plate, for the upper bearing 31, is formed with a 'notch 40 to accommodate the pinion 28, and a similar notch 402L is formed in the plate 39 for the lower bearing 31a, for a purpose to appear.

An inner U-shaped plate 41 is received snugly between the arms of the plate 39 and the arms of the two plates are secured t0- gether by screws or the like 42a. The bight portion 42 ofv this plate 41,y is shaped to cooperate with the correspondingportion of the plate 39, in forming a complete bearing for the shaft 27, and the plates 239-41 have their arms bent to provide co-operating shoulders 43H43, which limit the movement of their bight portions toward each other, so

that they cannot-bind upon the shafts.

The end of the U-shaped plate 41, toward the shaft 27 (upper bearing 31) is notched at 44 to accommodate the pinion 28. The corresponding portion of the lower bearing 31?l is Vnotched at 44a and this notch communicates with the notch a as shown in Fig. 5, the two notches accommodating a collar 45 which is suitably secured upon the shaft 27, for a purpose to appear.

The notch 44a is formed by bending por tions of the arms of the lower plate 41, inwardly toward each other as shown at 46 in liigs. 5 and 11. Moreover, these arms of both of the plates 41, have their free ends bent inwardly toward each other as shown at 47. rlhe portions 46-47 of the plate 41 (lower bearing 31a) are formed with alined openings in which a tube 48 is secured. vThis tube contains a bolt 49 which, by appropriate operating means 50, may be projected into any of a plurality of notches 51 with which the collar 45 is formed. Vhen the bolt 49 is engaged with any of these notches, the shaft 23 is held against turning` with respect to the sash 30. Thus, the sash cannot bodily shift from one side of the frame F toward the other side thereof, for instance, under the iniiuence of wind, after it has once been set at a desired position. To then prevent 'the pinions 28-28a from rolling along the rack bars 17-'20, a conventional sash-hold ing device such as that shown at D in Fig. 1, may be employed, said device being of course detachably connected with the sash 30 so that it will not interfere with reversal of the latter when desired.

Normaily, the bolt 49 is disengaged from viousiy its outer side, for effectively cleaning the same without danger and without eX- posure to the weather.

For 'Ventilating purposes, it. is often de sirable to shift the shafts 223-27 to a position between the vertical sides of the frame and to swing the sash an ang-le to 'the plane of the frame. The bolt v49 and one or another of the notches 51, together with the device D, serve 'to effectively hold the sash in its adjusted position.

as excellent results :are obtainable from the details disclosed, they are preferably followed. However, within vthe scope of the invention as claimed, variations may be made, and by slight changes, wood instead of metal, may be used for the sash and certain frame parts.
